Assessment of Impacts Paper Industrial Effluent on ground water quality

Water is an essential component for the survival of the eco systems and all the living organisms on the earth. Due to agricultural activities, rapid industrialization and growth in urban population, the water sources are being contaminated by anthropogenic activities. Keepingnbsp in view the rapid industrialization in East Godavari region, it is proposed to characterize the effluent water generated from the paper industry and ground water collected from the surrounding areas of the industry to assessnbsp the impact of paper industrial effluentnbsp on ground water quality .The present work is focused on characterization of effluent and ground water collectednbsp physiologicalnbsp parameters viz.,pH, EC,TDS,TH, TA, Chloride, Sulphate, Nitrate,nbsp Phosphate, Na, K,Ca,Mg for assessing the chemical contamination of water. Irrigation parameters like, Percent sodium, SAR, RSC, KR and MH are determined to verify the suitability of water for irrigation purposes. Further thenbsp waters are characterized for metal ions like Li,Be,Al,V,Cr,Mn,Fe,Co,Ni,Cu,Zn,As,Se,Rb,Sr,Ag, Cd, Cs, Ba,Pb to assess the metal toxicity. The waters are also characterized for Microbial species. The research results revealed that higher values of TDS, TA and TH in some water samples indicate the presence of soluble solids and alkalinity of water. Higher values of TH in some samples indicate the encrustation nature of waters which make the waters unsuitable for drinking and domestic purposes. Presence of pathogenic bacteria like E.coli, Enterobacter, Pseudomonas, Klebsiella and Basillus indicate the microbial contamination of water and hence these waters can cause waterborne diseases, if consumed for drinkingnbsp purposes. It is suggested that these waters are to be treated by using the available treatment methods to remove the chemical contamination and to subject the waters for disinfection methods to remove the microbial contamination befour use for drinking or domestic purposes

Complete surgical myocardial revascularization: shift of paradigm of the gold standard in the current era

Coronary artery bypass surgery is recommended for the patients with symptomatic coronary artery disease or patients having critical left main trunk stenosis. From the inception of the procedure it has undergone several modifications during different time periods evolving into the safe, durable and effective procedure that is to-day. Complete myocardial revascularization (CR) restores blood supply to all the territories in the myocardium that are ischemic because of narrowed blood vessels. Earlier clinical studies from the1980s showed that patients who had CR had better quality of life free of angina with less major adverse coronary events and had survival benefit when followed at 5 years and 10 years compared to the patients who had incomplete myocardial revascularization. According to the coronary artery surgery study registry the benefit is more pronounced when patients had severe triple vessel disease, class III-IV angina and decreased ejection fraction
